Dear Abhishek,<br><br>GrADS will not open netcdf-files straight away, if they don't follow the COARDS standard. Often it helps, when you create a control-file and open the data with xdfopen. See here:<br><a href="http://www.iges.org/grads/gadoc/gradcomdxdfopen.html">http://www.iges.org/grads/gadoc/gradcomdxdfopen.html</a><br>
<br>Furthermore, I have experienced that some files opened under GrADS 1.9b4, but not anymore under grads-2.0.a7. A simple option could be to try the older version, but this is probably not recommendable.<br><br>Good luck,<br>
